LakeAir's Approach to Industrial Air Purification.
LakeAir Industrial Air Purifiers fit best into the commercial / light industrial range. Our industrial air purifiers use HEPA . Electrostatic, and or Carbon filtration. For exceptionally clean air we offer a hybrid of both Electrostatic and HEPA. At the entry level, units from other manufacturers typically use a single blower and a MERV filter bag. This is sufficient for low smoke and moderate dust control. LakeAir industrial units approach indoor air contaminants from another angle.
- Instead of a bag filter with MERV 14 Efficiency (PM10 is 90% efficient and PM2.5 is 80%) we use ESP (Electrostatic) cells ( 97% efficient on both)
- Bag filters average 80, many times two per unit = 160 Square feet of media. LakeAir ESP filters a 230-square-foot collection area.
- 1 Large blower rated 2600 CFM @ .6 WG / 3000 CFM @ .4 WG. Lakeair Uses 4 blowers 3220 .6 WG (much less chance of total system failure
- The Bargain models have 2 speed switch LakeAir industrial air purifiers have variable speed and can be controlled by Bluetooth or building automation
- Bag filters need replacing anywhere from 1-6 months. LakeAir Filter cells are washed every 2-4 months

LakeAir Light Industrial Air Purification LA9- RC6 & RC8 7200 CFM
The LA9-RC8 is LakeAir’s largest stock unit. Understanding the product name goes a long way toward understanding the unit. The LA stands for LakeAir. The 9 represents the number of standard filter slots. The RC6 represents the number of reverse-curve blowers.
LA9-RC8-S9 Industrial Powerhouse
The LA9-RC8, loaded with nine 97% filter cells, can deliver up to 7200 CFM of air through the filter bank. Many times it is more efficient to run the LA9 at slightly lower speeds. This will vary from environment to environment. Using the high end of the LA9’s range will improve particle removal. Running the LA9 on a somewhat slower speed will help clear ultra-fine particles from the air
The true variable speed of the LA9 allows you, the shop owner or manager, to tune the air purification system to match your unique indoor air pollution challenges. The range if the LA9 is from 10 to 100%.
Other LA9 Options
If your air-cleaning needs do not require a 7200 CFM Beast, you can opt for a slightly less expensive model, such as the LA9-RC6. Taking that step down will save you over $1000. The LA9-RC6 still processes 5600 CFM of oil and dirt-laden air.
The actual volume of air cleaned ill
LA9 units have a wide range of prices, depending on the number of blowers and the type and number of filters. The range is roughly $12,000 – $7500. Call now for availability.

The Makeup of a LakeAir Electrostatic Filter Cell
LakeAir has been manufacturing electrostatic filter cells since around 1970. When the physical characteristics of the cell were designed, there were a few goals in mind.
- Low Ozone Emission
The primary contributor to ozone formation during cleaning is high voltage. As electricity passes through the air, it creates ozone, much like a lightning strike, but on a nanoscopic level. Our power supplies are balanced with the filter cells and produce so little ozone that, when the unit is equipped with a carbon filter, there is ZERO ozone emission. In a test in a very small space, 16″ x 16″ x 16″, the ozone emitted never exceeded 3 parts per million
- Narrow Collection Plate Spacing
- Filter Cell Longevity
There are good materials available to make electrostatic filter cells last a very long time. We know of filter cells that have been operating since 1974. The key materials are high-grade aluminum for ionizing and collection plates, and ceramic for high voltage insulators, GP03 fiberglass panels for what proof and moisture resistance, and white tungsten wire at 0.005 inches
- Why better material make a difference
The 3003-H-14 aluminum we use is thicker than bargain ESP filters, which likely use galvanized steel or 1100-O. Our aluminum is harder, stronger, and has a longer life
We use a Gold Standard insulator made of L-5 grade Steatite ceramic; other companies may use plastics or phenolics
GP03 is much stronger and more resilient than a GPO2, 0r 1 or paper-based phenolics
White Tungsten is a premier material; cheaper materials include black tungsten and stainless steel
Should I Add a Mechanical Mist and Oil Filter?
Adding an Oil Mist Prefilter is one of the smartest things you can do. The pre-filter will remove 90% of the oil, which is larger aerosols, averaging from 3 to 10 microns. The second filter is an electrostatic filter cell that removes 97% of the remaining oil. The third filter, or the second ESP, will polish the air, making it 99% cleaner than the originating shop air.
The other benefit of a prefilter is that it reduces overall maintenance time. The best practice is to have an extra set of prefilters. You simply swap them out once or twice a week. Be certain the replacement pre-filter is completely dry.
The electrostatic filters require more care. You must be certain not to bend any of the aluminum plates or break any of the tungsten wires. Properly maintained, an ESP filter cell will give 15+ years of use.
This hybrid system will produce slightly less air flow. We estimate for total volume with one pre-filter and 2 ESP filter cells to be 5760 CFM
Ultra Clean Air with the Super HEPA Hybrid
When you need air that is more than just ‘filtered’—when you need it clinically clean you run into a common problem: most HEPA systems choke out the airflow. We designed the Super HEPA Hybrid to solve that. By dialed-in engineering, we’ve hit the sweet spot at 3,500 CFM. It’s powerful enough to scrub a massive room, but slow enough to give the filters the ‘dwell time’ they need to actually do their job.”
The ESP Agglomerator: This is our secret weapon. The LakeAir ESP cell ionizes microscopic particles, forcing them to clump together. By the time the air hits the HEPA, it’s catching ‘bricks’ instead of ‘sand,’ making the whole system vastly more efficient.
True HEPA Filtration: This is the clinical seal. It captures 99.97% of particles down to 0.3 microns. Because of the first two stages, this HEPA stays clean and free-flowing much longer than standard units.
Activated Carbon Polishing: The final pass. We use activated carbon to stripped out the gases, chemicals, and medicinal odors, leaving the air totally neutral.
One System, More Applications Than Any Other
One of the strengths of LakeAir industrial air purifiers is flexibility. The same core platform can be configured to handle smoke, fine particulate, oil mist, odors, VOCs, ultra-clean air requirements, and germ control simply by changing the filter stack. Electrostatic, HEPA, carbon, mist elimination, and optional germicidal irradiation (UV-C) configurations can all be deployed in the same cabinet, allowing one system design to serve manufacturing floors, machine shops, kitchens, cigar lounges, clinics, and specialty commercial spaces.
This adaptability matters because air quality problems change over time. A shop that starts with smoke or oil mist may later need odor control, finer particulate removal, UV-C germicidal support, or higher cleanliness standards. LakeAir systems are designed to evolve with those needs rather than be replaced. That’s why many customers use the same LakeAir unit across multiple applications over its lifetime—by reconfiguring filters instead of buying a new machine.
Frequently Asked Questions:
An industrial air purifier is a high-airflow filtration system built to remove airborne contaminants that are common in commercial and light industrial spaces: smoke, oil mist, fine dust, odors, and VOCs. The goal is not just “fresh air,” but cleaner breathing air, less residue on equipment, better comfort, and better compliance outcomes when ventilation is part of the conversation.
Many entry-level industrial units use a single blower and disposable bag filters (often around MERV 14). That can be fine for general dust control, but it is a different class of machine. LakeAir systems are designed around higher static pressure capability, variable-speed control, and filter stacks that can be configured as electrostatic, HEPA, carbon/VOC, mist elimination, or hybrids. The result is a system that can be tuned to your contaminant type instead of forcing every problem through the same bag.
That really depends on the industrial environment and the expectations of cleanliness. If you have a little smoke and a moderate amount of dust, a bag filter may be fine. If you have moderate to light oil mist, then electrostatic filters are the choice. If you have heavier oil mist, a hybrid of a mechanical pre-filter and an electrostatic is the best choice.

“A common guideline for industrial oil‑mist areas is about 6–12 air changes per hour (ACH), but the actual requirement depends on your specific process, enclosure, and local regulations. In the U.S., OSHA sets exposure limits in 29 CFR 1910.1000 (Table Z‑1), and mineral oil mist typically has a limit of 5 mg/m³ as an 8‑hour TWA. Always confirm final requirements with your safety team or OSHA and, if needed, with an air‑quality specialist.”
“If you’d like help translating exposure limits into a target ACH and system size, call our air quality specialist at 800‑558‑9436.”
The answer to this question is not simple; it depends on several factors, including the room’s length, width, and height. The required air changes per hour. The type of indoor pollution to be removed. For example, in a space with a 20-foot ceiling and light oil or smoke, one LA9-RC8 can clean up to 3,600 square feet at 6 ACH.
